really? I thought is was less likely to, and I though the weight of the oil also plays a big part. I just got my oil changed and I was talking to one of the techs trying to get a better understanding and they said the synthetic was less likely to burn in general. I had used 5W20 regular oil last time and said to switch over to synthetic and they said to up the weight to 5W30 with the synthetic and it would perform well and it would be able to handle the abuse I put on my car.DarkSideAccord said:synthetic burns way more.. stick to mineral
